pipes, and relates particu arly to hose pipes com rising sections of metal pipe united by flexi 1e connections; and the invention consists in certain novel constructions and combinations of arts as will be hereinafter described and c aimed.

In the drawing Figure 1 is a side view of a hose p'pe embodying my invention, parts bein broken away. Fig. .1 is a side View part in section illustrating a number of meta lic pipes and couplings between the same. Fig. 2 is a longitudinal section on about line 2-2 of Fig. 1. Fig. 3 is a crosssection on about line 33 of Fig. 2, and Fig. 4

is a cross-section on about line 44 of Fig. 2. In the construction shown, the metallic ipes A are united by flexible hose len hs E, and the latter, except the section w 'ch receives the nozzle connection 0, may be of uniform diameter throughout as shown in Figs. 1 and 2 or may be tapered or sloped off at their ends at B as shown in Fig. 1 to receive the clampin coil D, the hose section receiving the noz e connection C being suitably formed to fit up over the corrugated nipple C of the said connection 0 and to be he thereon by the clamping coil E, as shown in Figs. 1 and 2 of the drawing.

The pipes A are provided on their outer sides near their ends with the flanges A which fit within the ends of the hose sections B, and engage therewith when the clam ing coils D are turned to position shown in igs. 1 and 2, and increase the security of connection.

The clamping coils D are conical or in the form of frustums, and when turned with a screw action upon the ends of the hose sectio'ns'B, bind said ends firmly in connection with the pipes A, as will be understood from Figs. 1 and 2 of the drawing.

The clamping coil E is turned with a screw action onto the end of the hose section receiving the nozzle connection O, and secures the parts firmly together, as will be understood from Fig. 1. The clamping coils D and E ma be of brass, or other suitable wire, and also employ within the hose section .bracing coils F and F, the coil F being arranged within the end section receiving the nozzle connection O, and the coils F within the other hose sections and extending throughout the length thereof Whereb to reinforce the said sections, revent t em from collapsing and reduce the liability of said coils being broken in use.

The bracing coils F and F, which ma be of brass wire 0 erate to kee the short ose sections of rub er from closmg up and shuttin off the water when making short turns or Tends in the manipulation of the hose pipe and they also compel the rubber conneotions to bend uniformly and on gradual curves.

The clamping coils D, it will be noticed have a diameter at their larger ends of such size as to receive the hose sections and at their other or small ends are of a diameter to fit u on the pipe sections E, which latter may e of galvanized iron, or other suitable material, as will be readily understood.

The flanges A on the pi es A are preferably formed by means 0 rounds of wire soldered in place on the pipes, as will be un derstood from the drawing.

Manifestly the hose sections may be of uniform diameter throughout as shown in Figs. 1 and 2, or they may be tapered at their ends to facilitate the application of the coils thereto as shown in Fig. 1.

1. The combination of a pipe section, a hose section fitted at its end on the end of the pipe section, such end of the hose section-bemg of substantially the same diameter as the body thereof, and a conical clamping coil formed at one end to fit upon the pipe section and at its other end to receive the hose section and tapered at such end whereby it may be screwed upon the hose section to and which tapers thence to its smaller clamp the same ilpon the pipe section, subpipe the pipe section, substantially as and tor the purposes set forth. end which embraces 2.
